This document was written by Claire Halleux, based on her own experience in Lubumbashi, in order to support anyone who wanted to help integrating administrative limits in the city of Lubumbashi. Suggestions and improvements are obviously welcome. After an additional data collection session at the beginning of January 2016, the administrative boundaries edition was completed during the first half of January 2016.

Please don't edit anymore those limits if you haven't acquired any additional reliable information beyond the ones previously displayed on this page.

This work needs to be done using JOSM and relations class of objects. If you are not familiar with both of them, please start familiarising with those notions first.

NB: The preferred option is to create new ways (detached from existing objects such as roads, rivers… for the admin boundaries.
Each administrative unit should be a closed way

What to do

In the table below, you’ll find 17 pdf files carrying the name of one or several quartiers (level 8). In each quartier’s file, you should find the description of the cells limits for this quartier.

They come in different “formats”, some are easy to read and identify, some might be much more difficult to find. Some files were even slightly “cut” by the scanner. Let’s exchange to find solutions and make it work.

We also need a place to mention on which files or quartiers we are currently working on, so we don’t duplicate the effort (see the table below).

Thanks a lot for your interest and looking forwards making this work together!

Finding the limits of each cellː

Using the relevant data sheet from the owncloud link, identify the streets that border the cell. The north, south, east and west as listed on the pdf may not be obvious as the city planning is not necessarily linear. It is useful to use the mapnik imagery layer to find these streets as you might want to filter out everything but admin divs in the data.

Filtering out other building, highway and landuse data

Open the filters panel, add a new filter and enter highway=*|building=*|landuse=*. Selecting this filter and then toggling inverse will alternately show you admin data or building, highway and landuse data.

Adding in admin boundaries

Create ways along the limits of your cell, with nodes at each corner. If there is already a way in existence, you may need to split it at the point at which your cell joins.

Once you have ways outlining your cell, you can tag your boundary by going to Presets | Relations | Boundaries. Enter the name and boundary type (this will be administrative). Then add in your Administrative Level. This will be 9 for cells (most likely) or 8 for quartiers. click New Relation.

You should now be in the Tags and Members tab. In the 'Role' box, add 'outer' for each of your ways.

Data table:

We used the data table that was displayed here to coordinate until December 2015 the administrative boundaries edition work. We listed download links for the paper scans, and put our names alongside the one we were working on. It's been removed as it had become outdated (see older version of this page from December 2015).
